Animals, sports, maps, cars, ships, movie stars! History, geography, art, and world culture! Stamps can be miniature works of art, treasured keepsakes, and rare collectibles. Campers dive into the world of the stamp, meet Owney the Dog, and discover his coast-to-coast rail journeys. They create their own Smithsonian-themed postcards, stamps, and group postal exhibit to share with family and friends at the end of the week.
